The Toronto Port Authority says there will be no departures from Billy Bishop Airport for the rest of the day. Flights from Porter and Air Canada are still arriving and while the ferry service will no longer take passengers to the airport, it will be shuttling travellers off to the mainland. Travellers are advised to contact their carriers for the latest updates regarding flight while those looking to pick up passengers at the airport can still do so by car or taxi.

The heavy rainfall has also caused some delays and cancellations at Toronto's airports. Peason International is reporting 79 cancelled flights as of 7:00 p.m., though it's uncertain how many of those cancellations were related to the storm. The airport warned travellers to expect more delays and cancellations, in a tweet.

We appreciate everyone's patience as we deal with affects of this storm. Delays and cancellations will continue through the evening.

Travellers flying to or from Pearson International are advised to call their airlines ahead of time for any changes. Toronto's island airport, Billy Bishop, is also warning travellers to check in advance for any changes to their flights here.

A low pressure trough is expected to cross Southern Ontario early Wednesday. Conditions will be favourable for thunderstorms to develop ahead of the trough overnight into Wednesday morning. Some of these storms could contain torrential downpours, damaging winds, and large hail.

From our compartment window, we could see a phalanx of police cars, fire trucks and EMS vehicles lined up along a roadway to our west. Although they were less than a hundred yards way, it was fairly apparent they couldn’t do anything until the water level outside dropped.

1. Avoid driving on roadways with standing water
2. Treat intersections without working signals as all-way-stops
3. Do not touch or handle any wires that may have come down during the storm
4. To contact police for non-emergency incidents call 416-808-2222, keeping 9-1-1 for emergencies
5. Stay clear of riverbanks as the walls will be very soft and unstable
6. Water levels will have risen and water will be fast-moving and dangerous

TTC CEO Andy Byford praised his staff for getting most of the TTC up and running for Tuesday morning's rush hour. "It's been a fantastic effort by my staff," he said at a press conference. "I pay tribute to myself," he added.

Byford also notes that the last stretch of affected track on the city's west side might be restored by the evening rush hour.

Toronto Hydro says that thousands of Torontonians are still without power and that the system is 'currently operating beyond capacity'. Toronto Hydro chief Anthony Haines urged that residents try to conserve power today and into the evening. "The system is not in normal working condition," he added.

He also said that they are working to restore power to all those affected but that it may take until tomorrow to restore power.
